Expandafoam

Closed cell polyethylene joint filler.

Description

Expandafoam is a flexible, readily compressible, closed-cell polyethylene joint filler supplied in sheet form and in rolls of rectangular sections. Expandafoam is available in a range of widths and thicknesses to suit common applications and can be pre-slit to assist in forming a slot to accept joint sealants. Expandafoam can also be supplied with a self adhesive backing.

Uses

Expandafoam is a closed-cell polyethylene joint filler for use as an expansion joint filler in brick and blockwork, isolation joints and hinge joints where a readily compressible low load transfer joint filler is required. Expandafoam is also used as back-up strips for elastomeric sealants placed in joints of concrete floors subject to foot traffic and light wheel loads. For joints subject to heavy loads or joints in water retaining structures Hydrocell should be used (see separate Technical Data Sheet).
